Imagine having a simple app（应用程序） that works like： When you need help， just open the app， touch the "notOK" button and a text message will be sent to five pre﹣selected（预先选定的）people， along with a location（位置）to show where you are． The message reads， Hey， I'm not OK． Please call me， text me， or come to find me．"

US teenagers Hannah Lucas， 15， and her brother Charie， 13， have created an app called notOK． People just need to pay ￥1.99（12.5yuan） each month to use it．

Hannah was inspired（启发） to create the app during a dark time in her life last year． She suffered from a disease that caused her to pass out at school． Other kids sometimes bullied （欺凌）her about this． She felt sad and wanted to find an app that would allow her to get help when she wasn't feeling OK．

She asked her brother Charlie， whose nickname is "Tech Support"， to find such an app． When they couldn't find they decided to create one themselves．

They came up with some designs for the app first Charie took a programming class last summer and built a website for the app． Hannah also shared her idea in her summer business class． Some app developers showed interest and decided to help her． At last， the app came out in the US and Canada on January 31．

Hannah is happy that her app is helping others． "It makes everything I went through last year worth it，" she said．
